I plan to travel to Quillan(southern france)from barcelona in early march to see the castle that was in the movie"THE NINTH GATE".I am having a hell of a time finding a train or bus going to Quillan from the surrounding points(carcasonnes,foix,perpignan or toulouse).Does anyone know of a way to get there from these points? If not,is it safe or even legal to hitch a ride?? thx
